Title: High voltage disconnecting switch
Inventor: KOPPE DENIS
IPC: H01H33/12
Filed: 1991-07-10
Abstract: ABSTRACT            HIGH VOLTAGE DISCONNECTING SWITCH    A semi-pantograph disconnecting switch (10) for a high voltage substation comprises a pick-up device (24) with a main conducting bar  (28),  and a contact head (22) having an insulating guide fork  (38),  a grip-type movable main contact (40),  and a whip-type movable arcing contact (42) associated with an operating mechanism (44). A trip lever (54) is controled by the bar (28) during the closing travel to unlock a finger (52) of the mechanism (44), bringing about movement of the whip towards a stationary arcing contact (34) at the same potential as the main bar  (28). Resetting of the mechanism (44) is performed automatically at the end of closing travel of the disconnecting switch (10).            The absence of an arc on the main bar  (28)  improves the reliability of the disconnecting switch (10).            Refer to figure 7.

Patent CA-2056936-A1 (CA)
Inventor: ESTERSON CHRISTOPHER D
IPC: B65G15/54
Filed: 1991-12-04
Abstract: Wire stock for connecting rods is run through the nip of a pair of obliquely toothed rolls having teeth which taper from one face of the roll towards the other, and have a larger radius at the tip than along the portions flanking the tip.  The angle of obliqueness matches the angle that a turn of a spiral wire will traverse the connecting rod. Round wire stock for the single-faceted spiral wires is run through the nip of a pair of rolls one of which has a cylindrical surface (i.e., a flat longitudinal profile), and the other of which has a circumferential groove with a slightly larger diameter than the round wire stock.  As the wire is flattened on one side, its curved side is broadened. As the resultingly single-faceted round wire is wound into flattened spiral form, it is spatially orientationally guided, so that the facet becomes located facing outwards.  The rods and flat spirals are conventionally assembled with one another and secured to one another at respective ends, to provide a balanced flat spiral woven wire conveyor belt with rounds of turns nested in concave oblique crimp notches on the connecting rods.

Patent CA-2064499-A1 (CA)
Inventor: DAVIS R ANDREW
IPC: E01C9/04
Filed: 1992-03-31
Abstract: A grade crossing system for extending a roadway across a railroad track comprises elongate elastomeric pad units which abut each side of the rails in the track but do not extend across the entire crossing.  The elas-tomeric pad units rest on the ties that carry the rails and have planar top surfaces that are coplanar with the tops of the rails.  The remainder of the crossing is filled with non-elastomeric panels that also rest on the ties and have planar top surfaces that are coplanar with the top surfaces of the rails.  The abutting edges of the pad units and the panels overlap such that the panels hold the pad units down against the ties and urge them against the sidewalls of the rail flanges.  Thus, mechan-ical fasteners are not required to hold the crossing elements in place.

Abstract: The present invention relates to a cable used to supply electric power to a pump for pumping crude oil from an oil well. It is consisted of an insulating layer, a resin sheath and a metallic sheath sequentially layered onto the surface of a conductor. A protective layer comprised by a wrapping of thermal resistant tape is formed at the surface of at least one of the insulating layer and the resin sheath. Due to the provision of this protective layer, it is possible to prevent the breakdown of the insulating layer and the formation of holes in the cable caused by pressure changes occurring when the cable is removed from an oil well within the high pressure environment.
